David Geffen is an entertainment industry mogul who founded two record firms and cofounded a movie studio. A college dropout, Geffen, who is dyslexic, used a fake UCLA degree to land a mailroom job at the William Morris Agency. He later founded Asylum Records and Geffen Records, launching careers of bands like The Eagles, Aerosmith and Guns N' Roses. In 1990 he sold Asylum to MCA for $550 million.

Four years later, with Steven Spielberg and Jeffrey Katzenberg, he raised $2 billion in one week to start movie studio DreamWorks SKG. Geffen owns a small stake in listed DreamWorks Animation. He also owns over $1 billion of Apple stock and one of the world's most valuable art collections. Says Geffen: "My mother taught me how not to get hustled."
